Yes, I tried to do the memtest as well, but my pc has no CD drive (not since my external sata CD drive failed me yesterday) and for some reason the only USB I have, besides my external HDD, is not bootable even after using the memtest86 install which should make it bootable.
I took a screen shot of the Disk Management drive map (not sure I did it right)
and I'll try that clean boot right away

Thanks a lot for response
